Question
Suppose you want to use z- test to verify the claim that = 3.5. Given a sample size of n = 32 and a level of significance of = 0.01, when should you reject Ho?
A. Reject Ho if the test statistic is greater than 1.96 or less than -1.96 B. Reject Ho if the test statistic is greater than 1.645 or less than -1.645 C. Reject Ho if the test statistic is greater than 2.33 or less than -2.33. D. Reject Ho if the test statistic is less than 2.575 E. Reject Ho if the test statistic is greater than 2.575 or less than -2.575.
Explanation / Answer
This will be a two tailed test and z critical value corresponding to 0.01 level of singificance in case of two tailed test
= -2.575, 2.575
Hence,
Reject Ho if the test statistic is greater than 2.575 or less than -2.575.
Option E is correct.
